The Sales Register (Report 5033) is configured to display specific transaction types and, by design, intentionally excludes certain vouchers. If your credit notes are missing, it is because they belong to a category that is filtered out of this particular report.

The following voucher types will not be displayed:
- Sales Credit Note
- Deduction Credit Note
- Cancel Bill Vouchers
This is the intended behavior of the report, as its filters are set to focus on other specific transaction types. There is no error; the report is functioning as designed.
